As part of the restoration on my 56 400, I had the transmission rebuilt locally here in Melbourne Australia by a rebuilder who has built a number of Ultramatics for various Packard owners here. From the very first time I started the engine, the transmission has leaked from around the converter area... I finally bought a two post lift recently so thought it time to remove the transmission to find out why it was leaking as the car is almost finished. What I found is that fluid is leaking from around one of the bolts holding the front bell housing to the transmission case as per the photo below. I am thinking that this is a simple matter of removing the bolt and applying some thread locker or sealer and problem is solved, but would like to see if anyone else has encountered a similar issue... Thanks. Attach file:

I would like to see the entire bolt pattern to get a better idea. Posted on: 2015/7/25 7:12 | |||

The self locking bolt has probably been installed elsewhere in the bellhousing pattern and can be identified by the cross scored head. If you don't have the correct bolt, put the present one back without the star washer and with a good sealant. Posted on: 2015/7/25 7:15 | |||

They were using the same torque for the aluminum as for the iron. This makes them highly susceptible to stripping. So I always used a 10lbft lower torque with blue Loctite and gasket sealer on the bell housing. Posted on: 2015/7/25 7:35 | |||

| Home away from home | Great, that is exactly where I was going. I did not see the locking bolt but wanted to see the entire bolts to verify. Ross hit it on the head, Very important to follow the Manual step by step. Switch these two bolts. Attach file:
